Just curious, are you using this setting. I’ll try and if I can make it though the day I’ll use it. My surface pro 8 has this feature and is still showing over actual capacity over design capacity, so I’m inclined to try it in the iPhone. What do others think?
Got a tip for us?

iPhone 15 Pro Max Are you limiting your iPhone 15 Pro battery to 80%?

Short answer I have is NO. I see no reason to even worry about the battery health of a phone as I consider it a consumable item. I also don't keep my phones over a couple years and sometimes I only go a year when I want to have some feature that the newer phones have.
I can tell you that 80% limit does not work. Mine charged to 86% when I took it out from the magsafe charger.
That's apparently by design. Every so often, it will charge to 100% to ensure it stays calibrated. I read that here.
If I would get an iPhone 15 I wouldn't set it to 80%. I always charge mine to 100%. Want to make sure I can make it through the day with no sweating about it. And my launch month iPhone 13 Pro Max's battery health is still at 94%.
So it would be a "No" for me as well.

No, I’m similar to others, I change every year so don’t need to. Plus I have apple care so if it did somehow go below 80% in 12 months I’ll be covered.
Absolutely! I set that immediately. I am rarely in situations where I am away from chargers for long enough to need to charge my battery to 100% daily. When I am in those situations I will adjust the setting to get the full charge.
No. I upgrade annually.
My 14 Pro has a battery health of 89%, and I don’t worry about it.

Why not just use the battery to it fullest extent and have it replaced when it starts dying?
No, just leaving Optimized Charging on and I upgrade every year.
I upgrade every 2-3 years. No I will not limit the battery.
Not planning to, because i'll get a new phone every 2 years.
Even if battery health goes to like 90%, i'll still have gotten more out of the battery than if i just charge to 80% every day..
Sure you could only charge to 100% when you actually need it... but will you remember or actually know beforehand?
Or will you end up below 20% or completely deplete the battery more often, which is also not good for the battery?

I upgrade it every year so that is not a concern for me, however I do understand why the feature would be useful for people that keep their phones for longer.
So none of you hand down your phones ... you just trade them in? Our phones could have a life of about 5-7 years within the family.
You paid paid for it so use it how you want, but do people not think about the 2nd, 3rd, 4th owner of phones? Even though you only keep it a year or 2, it will likely be resold to another user. If the original owner makes a very small effort to preserve the battery, then the next owner (or the reseller) won't have to replace the battery. So in the long term fewer batteries need to be produced.
Personally I've been trying to limit my charging for years using a smart switch that only charges my phone for 1 hour per night. My launch day 13 pro still has 93% battery health with heavy usage.

Honestly i'd just get the battery replaced before i give it to them, if needed.
But my new employer leases them... so i guess they are going "back" after 2 years
I do not believe charging up to 80% would meaningfully be that impactful.
I 5-12W slow charge overnight without case and 30W fast charge in the car with case for 0-50% battery within 30 mins.
If I was married with 4 kids this is what I could do when handing down devices. Replace batteries every 3 years.

So….let me get this straight. In order to make sure your battery holds its full capacity for the longest period of time, you’re going to…never run it for its longest period of time? A little self defeating, no?
In my opinion, this feature does make a lot of sense to use. Just not on the devices that can use it:
iPhones with 3000-4000+ mAh will, with normal use, still be perfectly usable in terms of battery health in 2-3 years, maybe even more.
But smaller iPhones and Apple devices, like iPhones mini, SE, AirPods, Watch, Pencil, have batteries with much lower capacities and will run through 1-2 full discharge cycles every day just with normal use (assuming you use them for a couple hours every day).
No, I’m not enabling it.

Can’t imagine what kind of mental health issue one has to suffer to use something like this on a consumer device where battery life is a critical usability factor and a battery replacement cost is negligible.
Truly surprised Apple added this option, but it probably boosts the sustainability angle.

I don't do it. My Pro max 13 still has great battery life after nearly three years of usage.
No. I used to sell my phone every year, but I went with the iPhone Upgrade Program several years back and don’t regret it. I’m giving up a bit of money and a lot of hassle.
I definitely see the advantage of maintaining battery life if I kept my phone, or handed it down, but it’s going back to Apple, and they’re not going to keep it in the phone anyway.
No. You set the 80% limit if you have a regular schedule where your phone is sitting on a charger. You disable it when you need the extra capacity for trips or outings.
